The characterization of the residual stress states in the specimen was carried out through X-ray diffraction using the sin2Ψ method.Nutritional condition impacts academic performance and cognitive development. In Peru, the prevalence of chronic undernutrition in children is 6.9%, increasing the risk of mortality and morbidity. This study aimed to develop an educational intervention to achieve an improvement in the healthy habits of children in a primary education school in Lima who live in vulnerable socioeconomic conditions. We conducted a prospective quasi-experimental pre-test and post-test study of an educational intervention. The information was collected through the adaptation of the WHO questionnaire "Global School-based Student Health Survey" (GSHS), with anthropometric variables, socioeconomic level, hygiene and eating habits. One hundred eight students from 5 to 13 years old from Arenitas del Mar School in Lima (Peru) participated. The educational intervention improved eating habits. Fruit and vegetable consumption 3 or more times/day (50.9%) increased after the educational intervention (49% vs. 62.9%,) p less then 0.0001. There was an improvement in hygiene habits, such as the frequency of handwashing with soap (32.4% vs. 63.9%) and the frequency of weekly bathing 4-6 times/week (25% vs. 47.5%) p less then 0.0001. The educational intervention promoted better healthy living behaviors, eating habits and hygiene. This kind of initiative is a crucial tool to establish healthy living habits.In the treatment of gingival recession, different surgical options have been described free gingival grafts (FGG), connective tissue Grafts (CTG), and a more recent technique, de-epithelialized free gingival graft (DFGG). They are not procedures exempt from the appearance of complications. Most publications refer to postoperative complications, and there is limited literature regarding the development of late complications (weeks or months). Our working group carried out a study to describe the development of late complications associated with the use of DFGG in comparison with CTG, providing an incidence rate and a classification. Sixty-eight patients with mucogingival problems were selected, and divided into two groups the Test Group, for which we used DFGG + Coronal Advancement Flap (CAF), and the Control Group (CTG + CAF). All patients were treated at the University of Seville's dental school to solve mucogingival problems for aesthetic and/or functional reasons. A classification is proposed based on its severity; Major and Minor. Major complications included reepithelialization of the graft, epithelial bands, cul-de-sac, epithelial cysts, and bone exostoses. Minor complications included the graft´s color changes and superficial revascularization. Late major complications were only associated with the use of the DFGG, and the late minor complications developed with the use of the DFGG were much higher than those associated with CTG. CTG appears to be a safer procedure than DFGG in terms of late complications.Sol-gel layers have been the subject of many studies in recent decades. However, very little information exists about layers in which carbon structures are developed in situ. Using the spin-coating method, we obtained thin iron-doped SiO2/C composite films. The results of Raman spectroscopy showed that our samples consisted of graphitic forms and polymers. The latter's contribution decreases with rising temperature. FTIR and EDS studies show changes in carbon distribution on top of the layer, depending on the sintering temperature. The samples sintered at 800 °C showed a significant increase in the contribution of carbon forms to the layer's surface. Therefore, high conductivity can be observed in this sample. The results of XPS spectroscopy showed that the contribution of sp3 hybridized carbon increases after etching. The total electrical conductivity, studied by a DC four-wire technique, increased with the temperature and showed almost linear characteristics with significant changes below 150 K. The reduced activation energy plot has a positive temperature coefficient, which is a characteristic property of the conductive polymers in a metallic regime of conductivity.Microorganisms, including pathogenic or opportunistic bacteria and fungi, may gain access to the uterus during breeding, and infectious endometritis plays a major role in equine subfertility. This study aimed to assess the post-breeding inflammatory response, endometrial culture, and embryo recovery of mares susceptible to persistent breeding-induced endometritis (PBIE) treated with plasma-rich (PRP) or -poor (PPP) plasma. Mares (n = 12) susceptible to PBIE had three cycles randomly assigned to receive intrauterine infusions of lactate ringer solution (LRS, control), or autologous PRP or PPP pre- (-48 and -24 h) and post-breeding (6 and 24 h). Mares were bred with fresh semen from one stallion. Intrauterine fluid accumulation (IUF) and endometrial neutrophils were assessed every 24 h up to 96 h post-breeding. https://www.selleckchem.com/products/d34-919.html Uterine cytokines (Ilβ, IL6, CXCL8, and IL10) were evaluated before (0 h), 6, and 24 h post-breeding, and endometrial culture three and nine days after breed. Embryo flushing was performed 8 days post-ovulation. Data were analyzed with mixed model, Tukey's post-hoc test, and multivariate regression. PRP treatment reduced endometrial neutrophils, post-breeding IUF, and pro-inflammatory cytokines when compared to control-assigned cycles, but not significantly different than PPP. Controls had a significantly higher percentage of positive bacterial cultures (33%) in comparison to PRP-assigned cycles (0%), whereas cycles treated with PPP were not significantly different from the other groups (25%). The PRP-assigned cycles had significantly greater embryo recovery rates (83%) than the control (33%), though not significantly different than PPP (60%). Plasma infusion reduced the duration and intensity of the post-breeding inflammatory response and improved embryo recovery in mares susceptible to PBIE. Platelets incrementally downregulate PBIE and appear to have a dose-dependent antimicrobial property.
